Roger Tsien's First Day as a Nobel Laureate

Tsien receives congratulations, and a hug, from Charles Zuker, a UCSD professor of biology and fellow Howard Hughes Medical Institute investigator. He had just arrived at his office on campus after finding out that he had become a Nobel laureate. Tsien, a professor of pharmacology, chemistry and biochemistry at UC San Diego and a Howard Hughes Medical Institute investigator, has dedicated his career to the development and application of fluorescent protein probes that enable scientists to monitor cellular function.
